Highlights

🐞 Bug fixes

• Fixed HTTP header conflict between Content-Length and Transfer-Encoding in res.send - by @​YuryShkoda in #4893

  Fixed the behavior of res.send() to prevent conflicts between Content-Length and Transfer-Encoding HTTP headers in responses. The Content-Length header in res.send() is now only added when a Transfer-Encoding header is not present, complying with the HTTP specification that states both headers should not coexist in the same response. ETag generation is unaffected by the presence of a Transfer-Encoding header - by @​cuishuang in #7459

• Upgrade qs to ^6.16.0, which fixes CVE-2026-2391 (GHSA-w7fw-mjwx-w883), CVE-2026-82417 (GHSA-4mjr-xmp4-gh2g) and CVE-2026-82562 (GHSA-x5fp-wj9c-mxmx): arrayLimit bypasses in comma parsing and a denial of service via an attacker-controlled isBuffer - by @​davetashner in #7057 and #7478, and @​cyphercodes in #7305

• Upgrade proxy-addr to ^2.0.8, which fixes CVE-2026-90711 - by @​lazerg in #7474

🚀 Improvements

• Allow conditional revalidation for QUERY requests. req.fresh previously only validated freshness for GET and HEAD requests, so QUERY responses never returned 304 despite a matching validator. Since QUERY is a safe, idempotent, and cacheable method that supports conditional requests, it is now included in the freshness check - by @​Cherry in #7366

  // QUERY /reports with If-None-Match: "12345"
  app.query('/reports', (req, res) => {
    res.set('ETag', '"12345"');
    res.send(results); // now responds 304 Not Modified
  });

• Improve HTML structure in res.redirect() responses when HTML format is accepted by adding <!DOCTYPE html>, <title>, and <body> tags for better browser compatibility - by @​Bernice55231 in #5167

• When calling app.render with options set to null, the locals object is handled correctly, preventing unexpected errors and making the method behave the same as when options is omitted or an empty object is passed - by AkaHarshit in #6903

  app.render('index', null, callback); // now works as expected

• Upgrade content-type to ^2.0.0, bringing a faster parser (~1.5x quicker Content-Type parsing/formatting in res.send()) along with a behavior change: res.send() now keeps any existing parameters when adding the charset and no longer throws on a Content-Type that fails to parse. type-is is upgraded to ^2.1.0 as part of the same change - by @​blakeembrey in #7234

  res.set('Content-Type', 'text/plain; foo=bar').send('hey');
  // -> Content-Type: text/plain; foo=bar; charset=utf-8

• The default error handler now logs the full error object instead of only its stack trace, so nested details such as Error.cause and library-specific properties (e.g. Sequelize's parent/original) are no longer swallowed - by @​Nitin-Mohapatra in #6464

• Upgrade content-disposition to ^2.0.1, which changes the Content-Disposition header emitted by res.download(), res.attachment(), and res.sendFile(): file names that are valid HTTP tokens are no longer wrapped in quotes. This is equivalent per RFC 6266, but applications asserting on the exact header bytes should update their expectations - by @​blakeembrey in #7233

  res.attachment('user.html');
  // before -> Content-Disposition: attachment; filename="user.html"
  // after  -> Content-Disposition: attachment; filename=user.html

Superseded by #31, which applied this update (with the rest of the Dependabot backlog) on top of current main, tested together. Closing.

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
